Alarm tone is digitally generated. The alarm is activated by an
external contact closure. A transformer-isolated line level output is
provided using an RCA jack on the rear panel. The unit operates on
120 volts AC. A small internal speaker provides a soft signal for
local feedback, useful when the alarm tone generator is remotely
located from the external speakers and amplifier.
The alarm tone automatically times out after thirty seconds. All of
these parameters can be customized at the factory.
